from mypyc.ir.ops import BasicBlock # Create a basic block basic_block = BasicBlock() # Add an operation to the basic block basic_block.append_op("ADD", 1, 2, "result") # Get the last operation in the basic block last_op = basic_block.ops[-1]In this example, we create a basic block and add an operation to it. The append_op method takes four arguments, the name of the operation, and the parameters. In this case, we add an addition operation (ADD) with parameters 1 and 2, and the result is stored in the variable "result". We then retrieve the last operation added to the basic block. This module is part of the MyPyC package, which is a compiler for Python that generates C code for execution. The MyPyC package aims to improve the performance of Python code by using static type annotations and generating optimized C code.
